WereChihuahua - Hentai Furry Form Hider (Patreon)

As I wrote in a comment you can hide the Furry Form by making them wear a costume. Problem is you need to go in CAS and manually change it for every outfits. I bring you this mod in case you want a quick way to instantly hide the Furry form of all the werewolves in game on all the outfits, since with this in they'll be forced a costume on them while in their wolf form 

FLAVOURS:

Bear Form

Bunny Form

Garden Gnome Form

BONUS:

Natalia Auditore Skyrim Werewolf Costume

You need the CC installed in your game

 Only pick one.

UPDATE:

Changed the way it works to avoid conflicts with mods changing the wereform walkstyle, now requires the xml injector (still only pick one)
